"I had a conversation with Dumbledore last night," he began, mostly because he needed somewhere to start and he wasn't sure where that was. "He made a comment about not letting the war get in the way if this was what we wanted -- too observant that man, sometimes. In any case, what it comes down to is that this is the problem, why I needed so much more time to think about things. I'm not sure I have any better answer for you now than I did before because I don't know what it is I want."

Maybe.
"It didn't seem helpful to discuss any of the rest if I don't know what I want in the first place."
